An understanding of soil moisture conditions is crucial for hydrological modeling and processes. However, few studies have compared the differences between dynamics content response to precipitation infiltration under different types vegetation on Qinghai-Tibet Plateau (QTP). In this study, a sensor was used continuous volumetric measurements during 2015 2016, with aim exploring variations in its across two (alpine meadow alpine shrub). Our results showed that temporal at surface (0–20 cm)...
Quantifying the variability and changes in phenology gross primary production (GPP) of alpine wetlands Qinghai–Tibetan Plateau under climate change is essential for assessing carbon (C) balance dynamics at regional global scales. In this study, situ eddy covariance (EC) flux tower observations remote sensing data were integrated with a modified, satellite-based vegetation photosynthesis model (VPM) to investigate change, phenology, GPP an wetland ecosystem, located Zoige, southwestern China....
Alpine shrub-meadow is an important ecosystem type on the Qinghai-Tibetan Plateau, providing a variety of services while supporting livelihoods pastoralists. However, there clear lack understanding changes in spatial patterns and alpine degradation. This study combined aerial photography ground surveys to investigate analyse impact degradation their services, relationships between services. The results showed that led fragmentation patchiness shrub-meadow, as evidenced by decrease proportion...
For the first time to our knowledge, we report here methane emissions by plant communities in alpine ecosystems Qinghai–Tibet Plateau. This has been achieved through long-term field observations from June 2003 July 2006 using a closed chamber technique. Strong emission at rate of 26.2±1.2 and 7.8±1.1 μg CH 4 m −2 h −1 was observed for grass community Kobresia humilis meadow Potentilla fruticosa meadow, respectively. A shrub consumed atmospheric 5.8±1.3 on regional basis; plants meadows...
Abstract Accurately quantifying evapotranspiration (ET) is crucial to fully understanding regional water resource management and potential feedbacks climate change in alpine grasslands. The quantitative relationships between ET environmental controls were investigated by a continuous eddy covariance dataset from June 2014 December 2016 over an Kobresia meadow on the northeastern Qinghai‐Tibetan Plateau. results showed that daily averaged 1.7± 1.5 mm/day (Mean ± 1 S.D.), with values of 2.9...
The Qinghai-Tibet Plateau (QTP) is particularly sensitive to global climate change, especially elevated temperatures, when compared with other ecosystems. However, few studies use long-term field measurements explore the interannual variations in plant biomass under fluctuations. Here, we examine of within two vegetation types (alpine meadow and alpine shrub) during 2008-2017 their relationships variables. following results were obtained. aboveground (AGB) belowground (BGB) response...
Grazing is an important modulator of both plant productivity and biodiversity in grassland community, yet how to determine a suitable grazing intensity alpine still controversy. Here, we explore the effects different intensities on biomass species composition, at community level functional group level, examines productivity-species richness relationship under four patterns: no (CK), light (LG), moderate grazing, (MG) heavy (HG), attempt grassland. The results were as follows. total...
Alpine grassland has very important water conservation function. Grassland degradation seriously affects the function; moreover, there is little understanding of change state during restoration. Our study aims to bridge this gap and improve our changes in soil moisture restoration process. In study, storage, vegetation, meteorology a non-degradation (grazing intensity 7.5 sheep/ha) severely degraded 12-18 were monitored Qinghai-Tibet Plateau for seven consecutive years. We used correlation,...
Introduction Alpine grasslands on the Tibetan Plateau are increasingly affected by grazing, resulting in complex changes soil nutrient availability. Methods This meta-analysis evaluates effects of different grazing intensities available nitrogen (AN), phosphorus (AP), and potassium (AK), identifies key environmental drivers. Results show that significantly increased AN 11.9% reduced AK 14.5%, while its impact AP was negligible. Light (LG) moderate (MG) both enhanced AN, with increases 6.88%...
Introduction Grazing activities were intensive in alpine grasslands and may alter the soil respiration rates across Tibetan Plateau. However, grazed grassland their underlying driving mechanisms remain unclear Methods In this study, we synthesized data from 38 groups to clarify response of CO 2 emission different grazing intensities. Results The effect size was 0.039 ± 0.051 activity on ecosystem rates, indicating that increased by 3.99%. Furthermore, sizes −0.146 0.209 0.076 0.046 steppes...
Qinghai Lake, the largest inland saline lake in China, plays a vital role wetland carbon cycling. However, structure and function of soil bacterial communities its estuarine nearshore wetlands remain unclear. This study examined effects type depth on diversity, community composition, functional potential Shaliu, Heima, Daotang River using high-throughput sequencing. The results showed that significantly influenced communities. Nearshore exhibited lower diversity 0–10 cm layer, while deeper...
Abstract Alpine wetlands and meadows across the Three Rivers Source Region (TRSR) store high soil organic carbon (SOC). However, information on factors affecting SOC storage is scanty. Herein, we investigated explored storage, including climate, properties above‐ belowground biomass, using 50 profiles TRSR Tibetan Plateau. The was 491.9 ± 158.5 Tg C 545.2 160.8 in alpine meadow, respectively. stock positively correlated with mean annual precipitation. no significant correlation between...
The Qinghai-Tibet plateau has the world's largest area of seasonally frozen ground. Here, shallow groundwater displays behavior that is distinct from elsewhere in world. In present study, we explore seasonal and interannual variation levels 2012 to 2016, attempt quantitatively evaluate relative influences individual driving factors on based boosted regression trees. results show that: (1) a scale, were characterized by double peak valley relationship, while an scale showed slightly downwards...
